JERUSALEM, June 29 (AFP) - Around 80 Palestinians minors in an Israeli prison north of Tel Aviv began a hunger strike Friday in protest over detention conditions, their lawyer said.

Adnan Rabih, who represents an association for the protection of minors, said the Telmond detainees are protesting at various measures of repression taken by the administration at the jail after a jail revolt Tuesday.

Prison warders intervened to crush the protest using tear gas grenades and truncheons, injuring nine detainees, two of them seriously.

Four detainees have since been put in solitary cells, and their friends are demanding they be returned, along with demands for the reinstatement of prior rights.
